1PFUZE100 family of regulators
2
3Required properties:
4- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
5- reg: I2C slave address
6
7Optional properties:
8- fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch
9  regulators to save power consumption. Attention, ensure that all important
10  regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"
11  property. If not present, the switched regulators are always on and can't be
12  disabled. This binding is a workaround to keep backward compatibility with
13  old dtb's which rely on the fact that the switched regulators are always on
14  and don't mark them explicit as "regulator-always-on".
15- fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all
16  power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
17  Use this option if the SoC should be powered off by external power
18  management IC (PMIC) on PMIC_STBY_REQ signal.
19  As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
20
21Required child node:
22- regulators: This is the list of child nodes that specify the regulator
23  initialization data for defined regulators. Please refer to below doc
24  Documentation/devicetree/bindings/regulator/regulator.txt.
25
26  The valid names for regulators are:
27  --PFUZE100
28  sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
29  --PFUZE200
30  sw1ab,sw2,sw3a,sw3b,swbst,vsnvs,vrefddr,vgen1~vgen6,coin
31  --PFUZE3000
32  sw1a,sw1b,sw2,sw3,swbst,vsnvs,vrefddr,vldo1,vldo2,vccsd,v33,vldo3,vldo4
33  --PFUZE3001
34  sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4
35
36Each regulator is defined using the standard binding for regulators.
